We've already talked some about EPC's, but as they are the bread and
butter of cluster computation we'll consider them in detail here. If
your computational work tends to consist of running a series of more or
less independent jobs on your computer, perhaps varying the parameters
(or perhaps not), then you are an obvious candidate for a compute
cluster. You are the most fortunate of souls, as well, because in most
cases you don't much care about the design details of the cluster.

There are many useful tasks that fall into this general category, but
perhaps the cleanest example of an EPC task is Monte Carlo calculations
and other forms of statistical simulation. This is near and dear to my
own heart as it is what I do as a physicist8.1.
